Table 1a: Assignment of values to reasons for absence
(values must be in the range of 0 to 255, see 3GPP TS 29.002 [15])
Values Reason for absence
0 - no paging response via the MSC
1 - IMSI detached
2 - roaming restriction
3 - deregistered in the HLR for non GPRS
4 - MS purged for non GPRS
5 - no paging response via the SGSN
6 - GPRS detached
7 - deregistered in the HLR for GPRS
8 - MS purged for GPRS
9 - Unidentified subscriber via the MSC
10 - Unidentified subscriber via the SGSN
11 - deregistered in the HSS/HLR for IMS
12 - no response via the IP-SM-GW
All 'non GPRS' reasons (except for roaming restriction) can be combined with all 'GPRS'
reasons and vice-versa
All other integer values are reserved.
